Miniature rose plant named Meimagul

ABSTRACT

A new and distinct variety of rose plant of the Miniature Class is provided which abundantly forms attractive bicolored double blossoms which exhibit a generally velvet red appearance with some yellow coloration when viewed from above. The plant is bushy, and forms very vigorous vegetation that is dense and semi-dull in appearance. The blossoms possess no fragrance. The plant is well adapted to pot forcing under light, and grows well on its own roots. The foliage is medium green in coloration and tends to be well-pointed.

SUMMARY OF THE INVENTION

The new variety of Miniature rose plant was created by artificialpollination wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) was theproduct of the pollination of the Bonfire Night variety (non-patented inthe United States) by the Meialfi variety (U.S. Plant Pat. No. 2,140).The Meialfi variety sometimes is known as the Zambra variety. The maleparent (i.e., the pollen parent) of the new variety was the RUGULvariety (non-patented in the United States). The parentage of the newvariety can be summarized as follows:

    (BONFIRE NIGHT×MEIALFI)×RUGUL.

The seeds resulting from the above pollination were sown and 301plantlets were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of Miniature rose plant of the presentinvention possesses the following combination of characteristics:

(a) forms in abundance attractive double bicolored blossoms whichexhibit a generally velvet red appearance with some yellow colorationwhen viewed from above,

(b) forms medium-green pointed foliage,

(c) exhibits a bushy growth habit,

(d) is well adapted to pot forcing under light, and

(e) grows well on its own roots.

The new variety well meets the needs of the horticultural industry. Itis particularly well-suited for use as attractive ornamentation in thelandscape.

The new variety has been found to undergo asexual propagation in Franceby a number of routes, including budding, grafting, cuttage. Asexualpropagation by cuttings as performed in France has shown that thecharacteristics of the new variety are strictly transmissible from onegeneration to another.

The new variety has been named the Meimagul variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety described herein were two years of age and wereobserved during September while growing on their own roots indoors atLeCannet des Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The terminology whichprecedes reference to the chart has been added to indicate thecorresponding colors in more common terms. The description is based ontwo year-old specimens of the new variety which were observed duringSeptember while growing on their own roots indoors at LeCannet desMaures, Var, France.
